Embrey Mill Mine Road Bridge Wins VTCA Award
Herndon, VA— Pennoni’s Transportation division just received the honor of the Virginia Transportation Construction Alliance (VTCA) Transportation Engineering Award in the non-DOT $10 million category for the Embrey Mill Mine Road Bridge. The award was presented to Pennoni’s Ahmad Faqiri, PE, of the firm’s Herndon, VA office, at the VTCA meeting in Richmond, VA at the beginning of the month.
The bridge is located in the Embrey Mill Community in the Rock Hill District of Stafford County, Virginia and received the award for its innovative and effective design using Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS).
Pennoni’s GRS-IBS solution optimized design by accelerating bridge construction and minimizing earthwork, wetland impact, construction cost and life-cycle cost. The Mine Road Bridge is a 120-foot-long prestressed AASHTO bulb-tee multi-girder bridge supported by GRS-IBS. Application of GRS-IBS, a Federal Highway Administration (FHWA) Every Day Counts Initiative, was the innovative solution that allowed for the construction of cost effective 30-foot tall abutments despite the low allowable soil pressure; thus, eliminating the need for costly deep foundations or the need for a multi-span conventional bridge.The 120-foot-long bridge approaches the upper limit of 140-foot maximum span length recommended by FHWA for GRS-IBS applications.
